Lionheart is the second studio album by English singer-songwriter Kate Bush. It was released on 10 November 1978, nine months after Bush's successful debut album The Kick Inside. Lionheart peaked at No. 6 on the UK Albums Chart (her only album not to make the top 5), and has been certified Platinum by the BPI.

The first single taken from the album, "Hammer Horror", missed the UK Top 40. The follow-up single, "Wow", was released on the back of Bush's UK tour and peaked at No. 14 in the UK singles chart. The album is among Bush's worst-reviewed, and Bush herself was reportedly not happy with the finished product, feeling it rushed.
